Hi ya'll,
when I plug a cord into my jack, the signal cuts in and out. Do the jacks wear out? Is it common?

I generally use a wireless airline guitar transmitter which is about as big as your thumb and does not cause any problem, probably because there is no side pull.

any comments?

thanks

Yes, the jack can "wear out". It's not a common thing, but I have had to replace them in the past.
